Given that the average distance from earth to the moon is = 384400 kilometers.
Now question says to find the distance in miles so we need to use conversion formula between kilometers and miles which is:
1.60934 KM = 1 mile
Then we just need to divide 384400 kilometers by 1.60934 to convert that value into miles.
384400/1.60934 = 238855.679968 miles
We also need to round answer to the nearest 100 miles.
So the final rounded answer will be 238900 miles.
